WebbTheorem: The sum of the first n powers of two is 2n – 1. Proof: By induction.Let P(n) be “the sum of the first n powers of two is 2n – 1.” We will show P(n) is true for all n ∈ ℕ. For our base case, we need to show P(0) is true, meaning the sum of the first zero powers of two is 20 – 1. Since the sum of the first zero powers of two is 0 = 20 – 1, we see WebbI am sure you can find a proof by induction if you look it up.
